合理施肥是提高水稻产量的主要措施之一,但如何做到经济有效的施用肥料,以获得稳定而高额的产量,则是历年来主要研究的问题。现在根据几年来调查及试验所得,提出以下意见,以供参考。一基肥要施用迟效速效的混合肥料施用基肥不但是为了增加土壤有机质、改良土壞,并且还要靠它不断分解放出氮、磷、钾等速效养分,以供水稻整个生长期的需要。同时还要依靠基肥来争取秧苗返青快,发棵
Reasonable fertilization is one of the main measures to increase rice production. However, how to apply fertilizers economically and efficiently to achieve stable and high yield is a major research issue over the years. Now, based on the survey and trial income obtained over the past few years, the following opinions are put forward for reference. A base fertilizer to be applied late and quick-effect compost Fertilization of the base fertilizer not only to increase the soil organic matter, improve soil damage, but also rely on it to decompose release of quick available nutrients such as nitrogen, phosphorus and potassium for the growth of rice throughout the growing needs. At the same time also rely on basal fertilizer to fight back quickly green seedlings, send trees
